The LTC3780 is a DC-DC-Auto-Up & Down-Voltage-Regulator-5-32V-to-1-24V-DC-Adjustable-Converter. My interest in this DC-DC switcher is to operate 19VDC laptops/notebooks and LCD TVs from 12V batteries/solar.
The DS3231SN is a low-cost, extremely accurate I²C real-time clock (RTC) with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. The device incorporates a battery input, and maintains accurate timekeeping.
The PIC microcontroller minimum system board / universal programmer seat, dual-function board, user-friendly development, support all PIC microcontroller line package. Board size: 106*52mm double-panel.
The FT232B is the 2nd generation of FTDIs popular USB UART device and the FT232BL is a lead free version of the FT232BM. The FT232BQ provides the same functionality as the FT232BL in a QFN-32 lead free package.
The TCS34725 is a RGB and Clear light sensing elements IR blocking filter integrated on-chip and localized to the color sensing photodiodes minimizes the IR spectral component of the incoming light allows color measurements to be made accurately.
It is a small built-in vibration motor Module. After input 5V current, you can control the ON / OFF or vibration intensity of the motor By digital signal or PWM signal.
